Is This Normal?

[Apple Allen]

I was using my Jubulee today to run a 5' rototiller. It was working hard and I noticed quite a bit of exhaust coming out of the oil-fill cap vent. I have never seen this before when I am doing light work like pulling a hay wagon. The tractor has real good oil pressure and compression. My exhaust system is a normal horizontal type and seems to be in good condition. Is this exhaust normal?

That's what the crankcase breather is there for.

Keep it full of water and oil and give it He double hocky sticks!!!!

Just means the old girl has a little blow by is all. If the crank case did not breath some you would have problems. That is why cars have what is call a PVC valve but now days the hose from it goes to the carb/fuel injection in some way so you never see that smoke that may come out of it on a car/truck
